Analyze

POST 
/fraud/analyze

The Analyze Fraud endpoint performs a synchronous, multi-signal fraud risk assessment on a form submission. Send mapped submission fields and receive a complete risk report in a single HTTP call.

Five intelligence sources are evaluated in parallel:

  • Email: deliverability, domain reputation, address signals
  • IP: geolocation, connection type, blocklist status
  • Content: gibberish and spam detection on name and message fields
  • Session: behavioral fingerprint derived from the Opportify frontend SDK
  • Velocity: per-identifier submission rate with anomaly detection

At least one of email or userIp must be provided.

Authentication & Security​

  • API Key: Pass your API key in the x-opportify-token header.
  • No Query Parameters: All fields are transmitted in the request body to prevent PII from appearing in access logs or cached URLs.
  • Request body size limit: 64 KB. Requests exceeding this limit are rejected with a 400 error.
